Question

How long after receiving the Hepatitis A inactivated vaccine and Diphtheria, Pertussis, and Tetanus vaccine should the next shot be administered?

Answer

Among these vaccines, only the MMR vaccine is a live attenuated vaccine, while the others are inactivated vaccines. For two or three vaccines, the interval between them needs to be 28 days. However, for the interval between live and inactivated vaccines, or between inactivated vaccines, only two weeks are required.
